IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Patent No. 216,581, dated June 17,1879; application filed February 1, 1879.

To all whom it may concern Be it known that 1, DAVID F. STAMBAUGH, ofNewton, in the county of Jasper and in the State of Illinois, haveinvented certain new and useful Improvements in Washing-Machines and dohereby declare that the following is a full, clear, and exactdescription of the invention, reference being had to the accompanyingdrawings, and to the letters of refer ence marked thereon, making a partof this specification.

My invention relates to certain improvements upon that class ofwashingmachines which have a swinging rubber pressed downward by springsand working over a washboard in the bottom of the box, as will behereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawings, in whichFigure 1 is a longitudinal vertical section of a washing-machineembodying my invention. Fig. 2 is a transverse vertical section of thesame. 7

A represents thewashing-machine box, of any suitable dimensions, andsupported upon legs B B, firmly secured to the sides of the box. In thebottom of the box is placed a wash-board, composed of a series of barsor slats, G 0, arranged in curved form at suitable distances apart, andsecured to side pieces, D D, which rest upon the bottom of the box. Tothe sides of the box are attached standards F F, the upper ends of whichare slotted and connected by a cross-bar, E. In the slots in thestandards F is placed a shaft or roller, G, which has a handle or crank,H, at one end, for rocking the same and operatin g the rubber connectedto said shaft.

The shaft or roller G is held down in the standards by means ofbearing-blocks a a and springs I I, the blocks being placed in the slotsin the standards and the springs bearing on top of said blocks. Eachspring I is made of a single piece of wire, bent in the center to form adouble foot, Z), which bears on top of the block a. The two ends of thewire are coiled to form the springs d d, and the extreme ends secured ate to the under side of the cross-bar E.

To the shaft or roller G are secured arms J, to which are attached sidepieces, K K, and in these side pieces a series of rollers, L, have theirbearings, said rollers being arranged on the arc of a circle tocorrespond with the curvature of the wash-board formed of the slats O.The slats O are grooved longitudinally on their upper sides, as shown atw, to present a better washing-surface, and yet retain all the strengthof the bars themselves.

At one or more points between the rollers L is a rubber strip, h,projecting below the rollers, and attached to a cross bar, M, fastenedin the side pieces, K K, as shown. One or more of these rubber strips,acting in conjunction with the rollers L, facilitate the washing andhasten the operation very materially.

The rubber formed by the rollers L and one or more of the strips h isoperated by a crank or handle, H, attached to one end of the shaft orroller Gr. v

In putting in and removing the clothes the rubber is held elevated bymeans of a lever, O, pivoted on top of one side of the box, as shown. a

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the wire springs I I, constructed as described, eachspring forming a double foot, I), and coils d, with arms 0, secured tothe cross-bar E, the roller or shaft G, slotted standards F, boxes 0arms J, side pieces, K, rollers L, and rubber strip or strips It,substantially as and for the purposes herein set forth. 1

In testimony that I claim the foregoing I have hereunto set my hand this16th day of January, 1879.

DAVID F. STAMBAUGH.
